Title: Projection type display device
Inventor: SONEHARA TOMIO
IPC: H04N5/74
Filed: 1987-12-15
Abstract: PURPOSE:To use a reflecting type light valve and, simultaneously, to obtain a full-color projecting type display device with a compact optical system and a little optical elements by using wavelength separating elements combined in a cross shape. CONSTITUTION:A cross-shaped wavelength separating element 101 is located in a position equivalent to respective reflecting type light valves 102. A projecting light 201 to be made incident on the reflecting type light valves 102 is emitted from a light source 103, and the light is separated from a modulated projecting light 203 by a separating means 202. The cross-shaped wave-shaped wavelength separating element 101 has two works to synthesize the modulating projecting light 203 two-dimensional-modulated by the light valves 102 corresponding to a color-separating light and, in addition, to separate the light source light to a color light. An image needs to be prepared so that the light valves reflected by the cross-shaped wavelength separating element 101 and the transmission light valves can be mutually made into mirror images. Thus, the light path length from respective reflecting type light valves 102 to a projecting lens can be made shortest, and the whole device can be made compact.

Title: Wavelength selecting optical switch
Inventor: SAKATA HAJIME
IPC: G02F1/313
Filed: 1993-12-16
Abstract: PURPOSE:To enable tuning to a wide band by providing gratings with periodic discrete structures and varying the discrete periods of the discrete gratings from each other in internal two regions. CONSTITUTION:The gratings 13 are constituted of the periodic discrete structures and, therefore, overall spectra in a reverse direction are periodic peaks. The waveguide mode propagating in the first waveguide 11 is subjected to reverse directional coupling by these discrete gratings and is converted to a waveguide mode 2 propagating the second waveguide 12 with reverse directional coupling efficiency. The periods of such discrete grating arrays are slightly varied to ZL, ZR in the two regions in the element, by which the peak intervals of the reverse directional coupling spectra in the right and left regions are varied in the two regions. The refractive indices of the first and/or the second waveguides 11, 12 are changed, by which the independent shifting of the reverse directional coupling peaks of the right and left two regions by a method of current implantation, etc., is executed.

Title: Electrophotography
Inventor: NISHIDE HIROO
IPC: G03G13/22
Filed: 1987-12-14
Abstract: PURPOSE:To prevent retransfer and to improve the gradation of image quality by forming an image after performing the reproduction of a high density part first and superposing the image obtained by performing the reproduction of a low density part before transferring at the time of performing multiple transfer. CONSTITUTION:The electrifying, exposing and developing processes of each color are repeated twice by changing acting conditions so as to separate the reproduction of the high density part from the low density part, and the reproduction of the high density part is previously performed. The reproduction of the high density part is performed by raising exposure and making a developing bias high and the reproduction of the low density part is performed contrary to the above-mentioned manner. In the reproduction of the high density, the range of developed density is narrowed and the area of the image TH is small. And this small image TH is transferred from a sensitive material 1 on paper P. Since the image area is large and already developed toner exists in the low density part TL, the toner transferred once seldom contacts with the sensitive material 1 again and the retransfer hardly occurs. Thus, most of the toner is transferred on the paper and the gradation of the image quality is improved.

Title: Amplifier circuit with muting function
Inventor: TANAKA YOSHIAKI
IPC: H03F3/45
Filed: 1988-12-14
Abstract: PURPOSE:To ensure a sure muting action even though the ON resistance of a muting transistor TR is conventional one by saturating a TR forming an input circuit to apply a muting action by means of a newly added 2nd muting circuit in addition to the muting action of the muting TR. CONSTITUTION:When a mute control signal is inputted to a mute control terminal 3, a muting TR Q12 is turned on together with an emitter grounded TR Q15 also turned on. Then the pnp TR Q13 and Q14 are turned on to completely bypass the constant radio waves 12 and 13. As a result, both TR Q13 and Q14 are saturated and the bases of the TR Q6 and Q7 forming a differential pair are set at the voltage levels equal to the emitter-collector voltage level set at saturation of each TR and lower than the steady level. In such a constitution, an input circuit consisting of the TR Q8 and Q10, the resistances R4 and R6, the transistors TR Q9 and Q11, and the resistances R5, R7 and R8 becomes inactive and is muted. Thus a sure muting action is ensured.

Title: Speech encoder
Inventor: TOMITA YOSHIHIRO
IPC: G10L19/08
Filed: 1991-11-30
Abstract: PURPOSE:To reduce the size of each fundamental code book and to decrease the number of bits of an encoding output by classifying sound sources for white noises by characteristics. CONSTITUTION:A code excitation encoding system put the sound source for the white noise and an impulsive sound source together to reproduce a speech signal equivalent to a speech. At this time, the fundamental code book as the white noise sound source is constituted as plural fundamental code books 20-1-20-n by the characteristics. A characteristic selection control part 21 cooperates with an error minimization control part 14, and selects and outputs one of the fundamental code books 20-1-20-n to a selection part 22 as a characteristic-classified fundamental code book containing one code vector corresponding to the minimum error among error outputs from a subtraction part 16. Consequently, the speech encoder operates by using a vector group included in a small partial group, so the number of bits constituting a code Cout may be small and speech encoding with high reproduction fidelity becomes possible.

Title: Phase locked loop circuit
Inventor: TANAKA SHINICHI
IPC: H03L7/08
Filed: 1991-12-02
Abstract: PURPOSE:To obtain an accurate synchronizing signal regardless of a secular change or an effect of an ambient temperature by comparing a self-running frequency from a VCO with a reference self-running frequency so as to control the VCO. CONSTITUTION:A reproduction signal from an optical disk is binarized and the phase is compared with a clock outputted from a VCO 7 at a phase comparator circuit 4 and the VCO 7 is subject to PLL control in response to a phase deviation via a charge pump circuit 5 and a synchronizing signal synchronously with a binarized signal is outputted. When the signal is not reproduced and no binarized signal is inputted to the circuit 4, the VCO 7 outputs a self-running frequency and the frequency is counted by a frequency counter 1 and compared with a reference frequency at a frequency comparator circuit 2, the VCO 7 is controlled in response to the result of comparison and the VCO 7 outputs the self-running frequency signal with a prescribed frequency independently of a secular change or an effect of an ambient temperature at all times. Thus, the accurate synchronizing signal is always obtained independently of a secular change or an effect of an ambient temperature.
